IMPROVEMENT IN HARVESTERS.

Specification forming part of Letters Patent No. 219,795, datedSeptember 23, 1879; applicationfiled June 21,1879.

To all whom it may concern: v

Be it known that I, SAMUEL D. BATES, of Lewislourg, in the county ofUnion and State of Pennsylvania, have invented certain new and usefulImprovements in Harvesting-Machines; and I do hereby declare that thefollowing is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to letters of reference marked thereon, which form a part of thisspecification.

Figure 1 is a perspective of my improved harvester. Fig. 2 is atransverse section of the machine immediately inside of the devices foradjusting the main frame. Fig. 3 is an elevation of the driving-gearcasing. Fig. 4 is a transverse section, showing the tilting devices.Fig. 5 is a side elevation of the drivers seat. Fig. 6 is atopplan viewof the devices for securing the pitman. Fig. 7 is a transverse section,showing the mechanism for operating the rakes and the cutters. Fig. 8 isa side elevation of the devices for adj usting the platform on thecarrying-wheel. Figs. 9, 10, 11, 12, and 13 are detail views.

In the drawings, the main frame is shown as composed of an outside bar,A, an inside bar, A an intermediate bar or girt, A a front bar, A and arear bar, A all of which parts may be cast in one piece.

The draft-frame iscomposed of the tongue B, pivoted to thefront bar, Aof the main frame at a, the brace B, pivoted to the inner front cornerof the main frame at a, and the cross-piece or girt B The cross-piece Bof the draft-frame is situated in front of the driving-wheel, and itextends outside thereof to a suitable distance, to assist in supportingthe drivers seat, as will be more fully explained.

The cutter-frame is permanently secured to the main frame at the innerside of the latter. It is composed of the finger-bar O, the outer shoe,C the inner shoe, G and the divider O and it is mounted at the inner endupon the grain-wheel G.

The main frame and the cutter-frame are arranged to be tilted relativeto the draftframe by means of the following devices: Eis

a standard or upright attached to or formed with the main frame upon theoutside bar, A. E is a tilting lever pivoted to'the standard E, andcarrying a rocking-arm, e. The tongue B is pivoted to the main frame ata point some distance from its rear end, so that said end shall projectacross the front bar, A to a point nearly in the vertical line of thearm 0. F. is a link pivoted to the outer end of arm 0 and to the rearend of the tongue; and it will be seen that by means of the lever E thecutter-frame and the main frame can be tilted or rocked upon itssupporting-wheels.

The standard E and lever E are provided with suitable ratchet and paw],to hold the lever in any desired position.

F represents the main carrying" and driving wheel, mounted loosely uponthe main axle f. The main frame A A A A is supported upon the axle ofthe driving-wheel by means of a quadrant-plate or intermediate frame, G,which is pivoted outside the bar A at g, in rear of the axle f, andwhich, near its front or curved side, is permanently secured to theaxle.

The following devices serve to raise and lower the main frame and thecutter-frame relative to the main axle f. G is a liftinglever, supportedupon the axle or upon an extension thereof inside the quadrant G andabove the main frame. It is provided with a short arm, g to which alink, 9 is pivoted, which link is also pivoted to the main frame.

'11 is a ratcheted segment or standard secured to the quadrant G, andadapted 'to engage with a spring-pawl carried by lever G, and arrangedto hold the lever in any desired position. a

H is a curved standard secured to the main frame, and situated in frontof the; quadrant G. It is formed with a groove adapted to receive andguide the quadrant.

I I is a casing formed with or. attached to the quadrant. Within thelargerpart I is mounted the spur-wheel '5, which drives the variousparts of the mechauism;'aud within the part I is mounted a spur-pinion,6 mesh ing with the wheel t; .L

The quadrant G vibrates about the axis of pinion i.

It will now be seen that by means'of lever G the main frame andfinger-bar frame can be elevated or lowered relative to the axle,

and that by means of the parts G I I the driving and the driven partswill be in constant engagement; and, moreover, that combining in themanner described the lifting-lever (.l, permanently pivoted in reach ofthe operator, with the main-frame, the axle, and thequadrant orintermediate frame G pivoted to both axle and main frame around theshaft K, I have overcome the difliculties met with in attempting toconstruct one-wheeled harvesters (similar to that shown) so that theirmain frames could be readily raised or lowered.

It will be further seen that I have attached the lifting-lever at afixed point (which is a greatly desirable matter) by pivoting it to theaxle, which is projected inward to receive it.

In order to hold the lever in any position, I attach the ratchet IIrigidly to the axle, and to the quadrant or intermediate frame (it, amlthus I avoid the necessity ofthe supplemental devices hitherto employed,which are attached to the main frame or the tongue-frame, being able tomount both lever and ratchet together at a fixed point on the axle.

The spur-wheel z'is loose upon the axle f, and is provided withratchet-teeth adapted to engage with a springpawl, 1' carried by aplate, 2', secured to the main wheel F. Pilr ion i rotates thedriving-shaft K, which is mounted in thejournal boxes or bearings A andA on a line in rear of the axle of the driving-wheel, and carries at itsinner end a bevel-wheel, K, for operating the cutters, and a spur-wheel,K, for driving the rake.

L is a crank-shaft mounted in the box A, carryingat its rear end abevel-pinion, I, meshing with bevel-wheel K, and at its front end itcarries the erank-wheel I, to which is attached the pitman I, whichreeiprocates the cutterbar The end of the pitman is inserted in the eyeof the cutter-bar, as shown at I, and, in order to permit its beingreadily attached and detached, I combine with it the following devices.

M is a rod having a large eccentric head, or, at the rearend, and ahead, in, at the front end. This rod is mounted and adapted to rotatcand rtwiproeate in a box or casing, M, which is secured to the upperface of the outer shoe, 0.

M is a coiled spring situated in the casing M, and arranged to bearagainst the rod M so as to thrust it toward the pitman 1 the rod beingmounted in or near the line of the pitmans attachment to the cutter-bar.The head at comes sufliciently near to prevent escape of the pitman, andyet allows it (the pitman) to be removed, but does not interfere with itin its movements.

When it is desired to remove the pitman the rod M is drawn outward, andit is held out by means of a stop, M, until the pitman is replaced.

By mounting the look at a stationary point, (as upon the shoe,) and byarranging it so as to bear directly toward the pitman, and so that itcan reciprocate longitudinally, I avoid the necessity of many of thedevices required when the lock is attached to the pitman or cutter-bar,and also of the space required, if the lock be hinged or pivoted, so asto swing laterally or vertically. If the lock be arranged with a springbeneath it, it occupies much room vertically, and tends to clog withstraw and stubble.

N represents the rakes attached to an arm, N, which is pivoted to arake-head, N. The rake/head is secured to avertical shaft, which ismounted in the standard or frame 00, and carries at its lower end abevel-wheel, N

1 is a short shaft projecting from thestandards 0, and upon it aremounted the spurwheel P and the bevel-pinion P secured together, thebevel-pinion P meshing with the wheel N. \Vhecl P receives its motionfrom the pinion K on shaft K through an intermediate idIer-pulley, P

is the grain-wheel. It is mounted on the stud-shaft r, and is arrangedso as to readily adjust the platform to any desired distance from theground. I

The stud-shaft r is rigidly secured to a slide, It, which is providedeither with a screwthreaded vertical aperture or with a nut, as shown atr.

S is a screw-rod supported in a bracket, S, secured to the platform, andthe rod is prevented from reciprocating by means of a collar or othersuitable device. It engages with the sliding support R of thegrain-wheel, and by turning the rod S theplatform can be raised orlowered to the desired position. The bracket S is cast with the legs S Sadapted to retain the slide It in proper position and to guide it in itsvertical movements. The screwrod is squared at its upper end, so that itcan be readily operated by a key or wrench.

T is the drivers seat. It-is hinged to the main axlef, or to anextension thereof, outside of the driving-wheel F, by means of thevertical support T, which is arranged to have more or less play aroundthe axle.

U is a rod, mounted loosely upon the girt or cross-piece 13 of thetongue-frame by means of an enlarged head, U. Vis a pipe, into the lowerend of which the rod U is inserted, and which is hinged to the side ofthe (II'lVGPS seat, near its upper end. V is a coiled spring placedaround rod U within the pipe V, and arranged to hold the pipe forwardand downward, but to form a flexible connection between the pipe androd. When thus mounted the seat is firmly supported, but at the sametime is permitted to have all desirable movements.

The pipe is provided with several perforations, so that the point ofhinging to the seat can be varied, as may be desired.

In order to construct a self-raking reaper of the character shown in ascompact form as possible, it is necessary to so arrange the parts thatthe rakes while in operation come in close proximity to one of thehorses; and to prevent the horse from coming in contact with the rake,

I attach the double-tree to the tonguein the following manner W, Fig.10, represents a plate, which is secured to the tongue B, and which hasa recess formed in its rear end, and ears w to at the rear corners. Wisa plate secured to the double-tree, and provided at the rear end with adownwardly and forwardly curved lip, to. When the double-tree isattached to the tongue the plate W lies upon the plate W, and the lip wis inserted in the recess in plate W, so that the double-tree canoscillate to a limited extent around the bolt, but not far enough topermit the off horse to come into the path of the rake, the extent ofthe movement being limited by the ears to w, and it will be seen that bydevices constructed and arranged as described, the horse that is nearerthe rake will bechecked in any backward movement to which he may beliable and be prevented from getting back beyond a limited extent.

X represents the grain-platform. It is made of paper prepared to besufficiently strong and durable and to resist the action of theelements.

A represents a brace cast in one piece with the boxes A" and A andarranged to prevent any bending or sagging of the frame or any crampingor binding of the shaft K in its bearings.

I am aware that sleeves and sleeve-bearings have been heretofore used,and I do not wish to be understood as claiming such devices as myinvention 5 but I have found that a harvester-frame of the constructionI have shown and described herein is liable to sag or bend on linesbetween the journals A" and A of shaft K; and I have further found thata brace similar to that shown at A Fig. 13, cast in one piece with saidjournals, effectually obviates the objections named, but that asleeveformed apart from the journals and placed around the shaft and betweenthe journals does not materially strengthen the frame; nor do I claim inthis application either the devices which I have shown for transmittingpower from the pinion-shaft to the raking apparatus or a grain-platformconstructed of paper, as I have prepared, and am about to file, aseparate application, in which I claim as my invention said device andplatform.

What I claim is- 1. In a harvester, the combination of a main carryingand driving wheel, a.main driving or pinion shaft rotated by saidcarrying and driving wheel, and mounted in rear of the axle of saidcarrying-wheel, an intermediate plate or frame which vibrates about theaxis of the carrying and driving wheel, a main frame connected with saidintermediate frame by pivotal connection on a line in rear of the mainaxle, and vibrating about the axis of the driving or pinion shaft, and alifting-lever pivoted in front of said driving-shaft and connected withand supporting the front part of the main frame, substantially as setforth.

2. In a one-wheeled harvester, the combination, with the main frame andthe main axle, of a lifting-lever pivoted on said axle, and arranged tosupport the main frame, substantially as set forth.

3. In combination with the main carrying and driving wheel, the maindriving or pinion shaft, an intermediate plate or frame vibrating aboutthe axis of the drivingwheel, the main frame hinged to said intermediateplate or frame, and the lifting-lever pivoted upon the axle, a ratchetarranged to engage with the lifting-lever and attached to theaxle-rigidly, whereby it is made stationary relatively to the axis aboutwhich the lifting-lever vibrates, substantially as set forth.

4. In a harvester, a main frame upon which is mounted the driving-gear,and which is arranged, substantially as set forth, to support at itsinner side the raking apparatus and grain-platform, and at its outerside the driving-wheel in vertical position, and havingbearings for thedriving-shaft arranged on a line transverse to the inner side andtheouter side of the main frame, in combination with a brace, A rigidlyattached to or formed with said frame, substantially as set forth.

5. In combination with the drivers seat mounted upon the axle loosely,whereby it can rotate by the Weight of the driver, a spring secured atone end to the machine at a point stationary relatively to the seat, andarranged substantially as set forth, to return the seat, to its normalposition.

6. In combination with the drivers seat, mounted" upon the axle loosely,whereby it can rotate by the weight of the driver, a brace pivoted tothe seat or seat-support at a point above the axle, and constructed oftwo parts connected together by a spring, whereby the parts of the braceare made to slide longitudinally relatively to each other, substantiallyas set forth.

7. In combination with the cutter-bar and the pitman, a longitudinally-reciprocating look, a spring, and a stop, whereby the lock is heldagainst or away from the pitman, substantially as set forth.

8. In a harvester, the combination, with the cutter-bar and the rakingapparatus, both mounted in front of the axle of the carrying and drivingwheel, the tongue and the doubletree, of the stoppil'lg-plates W and W,constructed and arranged as specified.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
